The proposed study is a randomized control trial evaluating the efficacy of two training programs in increasing physician identification, documentation, and motivation of overweight children. Pediatric primary care physicians will be recruited from the College of Physician and Surgeons of Ontario and randomized into two practice-based interventions (behavioural/educational) which are a one-time training attendance. The educational intervention will focus on the medical management of pediatric obesity, the use of Body Mass Index charts, and information about how obese children would like to be approached by their physicians. The behavioural intervention will incorporate Motivational Interviewing tools in addition to an abbreviated training program received by the educational intervention group.
